Flame Spray Pyrolysis Synthesis of NiFe/TiO2 for Catalytic Deoxygenation in Biojet Fuel Production

Flame spray pyrolysis (FSP) was employed to synthesize a novel NiFe bimetallic catalyst with enhanced deoxygenation performance for biojet fuel production. The FSP method enables the rapid, one-step formation of bimetallic catalyst with uniform metal dispersion and controlled nanostructure. Catalytic deoxygenation was performed on trimethylolpropane trioleate (TMPTO) under nitrogen atmosphere at ambient pressure, targeting hydrocarbon products in the C8-C16 range. Comparative analysis with conventionally impregnated catalysts was done to assess the advantages of FSP in tailoring catalyst structure, improving metal dispersion and enhancing deoxygenation activity. This work provides a promising synthesis method for developing a rapid catalyst production system for biojet fuel production and lays the groundwork for the development of other FSP- synthesized bimetallic catalysts.
